=== A. Full-provisioned test card (recommended for realistic POS tests) ===
* Create a card that a processor/issuer issues (virtual card) and supports provisioning to Google Pay. Example: use Stripe Issuing or a card-issuing partner that supports Google Pay provisioning and tokenization (Visa/MC network tokenization). This requires a business account and KYC but gives a real token that Google will accept and the card can be used at real POS/online merchants (subject to funding).

B. Developer sandbox / Local integration testing (fast, limited to dev flows)
* Use Google Pay test environment + test card numbers for web & Android to test merchant payment flows (authors of the merchant code use environment: "TEST"). This validates integration (button, tokenization JSON, server code), but doesn’t create a Google Wallet “payment card” in your personal account for production checkouts.

C. End-to-end checkout testing on merchants (Booking/Takealot/etc.)
* You must test against merchant staging/sandbox or with each merchant’s test environment. You cannot safely or ethically use production merchant sites with fake cards.
